Wrongly assumed unused variable

[TrueCarry]

Contract compiles if query id is declared here. Throws error if query id commented out. I have another query_id declaration inside one of the if branches, this could be related.

It's not clear how to reproduce the problem, can you provide a code example?

Can't remember exact details, but it was something like

int query_id = ...
if (x) {
    int query_id = ...
}

call_func(query_id)
